1. Purpose and characteristics
The gas mask is a kind of respiratory protective equipment used by the synthetic . It is used to protect the face, eyes and respiratory tract of personnel from toxic and radioactive contamination when being attacked by chemical weapons and performing tasks in toxic and radioactive areas. It can also be used in industrial protection and other places. However, it is prohibited to use it in oxygen and carbon monoxide environment.
The sealing frame of the mask is arc-shaped and anti-folded, which is comfortable to wear and easy to be airtight. The mask material has excellent resistance to the penetration of poison droplets and washability. The outer edge of the cover body has a convex edge, which can match with the anti-virus head cover.
The six headbands can be adjusted at will, but they must be properly tightened.
The two round eyelets of the mask can match the optical equipment. The lens is made of optical plastic, and the surface is coated with wear-resistant coating, which has good optical properties, impact resistance and friction resistance.
